While it is not hurting anything, why do you have the computerspec structure if you are using the member variables individually? I would think you'd want something like:
struct computerspec
{
int compnum;
int ram;
int hdisk;
};
void main( void )
{
computerspec compuspec;
compuspec.compnum = 1;
compuspec.ram = 1024;
compuspec.hdisk = 80;
out << compuspec;
compuspec.compnum = 2;
compuspec.ram = 4096;
compuspec.hdisk = 40;
out << compuspec;
...
compuspec.compnum = -1;
compuspec.ram = 0;
compuspec.hdisk = 0;
out << compuspec;
out.close();
...
do
{
in << compuspec;
} while (compuspec.compnum != -1);
}Note that this is untested and may not be syntactically correct but I am just trying to give you an idea.

I am farily new to c++ and have been trying to compile something but it is giving errors about converting the two different types of char. Is there anyway that I can actually convert the char to a char* or have I got completley the wrong idea?

I think that you are off base.... post the code that you are having a problem with so we can help you better.

CIni ini;
ini.SetPathName(_T("D:\\Programs\\Microsoft Visual Studio\\MyProjects\\Prog12\\Debug\\IniDemo.ini"));
char test = ini.GetChar(_T("History"), _T("Input"), TCHAR("NoneSet"));
char* Program = "";
char* Paramaters = "";
char* workingDirectory = "";
// Now just use ShellExecute to run it
ShellExecute( NULL, "open", Program, Paramaters, workingDirectory, SW_SHOW );
The char test is the one that I need to be char* otherwise the ShellExecute will not work properly. I dont really understand all of that code yet which is probably why I cant do it correctly.

Since test is not being used, why do you need it at all?
What does CIni::GetChar() return? More importantly, what is the third parameter supposed to be? I'm not sure why the class differentiates between getting a char vs. getting a string, but in any case, you need to change your code to the following in order to pacify the compiler:
char test = ini.GetChar(_T("History"), _T("Input"), ' ');Why are you mixing _T() and TCHAR()? That in itself doesn't hurt anything but it does make your code hard to read.

The information for the shellexecute is going to be stored in an ini file so at the moment I am just testing getting the information from an ini file which is why the char test is there but now I need it to be a char* so I can actually use it in the shellexecute as when I compile it says shellexecute can only use char* and not char.

You cannot use the GetChar() method to retrieve a char* value. Which parameter of ShellExecute() is in error?

The Program, Paramaters and working directory all do not work if its just char.

Right. ShellExecute() does not use any char parameters. Without seeing the code that is in error, I can't provide anything useful.

What do you mean the code that is in error? The code I posted above is the only code I have in the program at the moment. Do you want the actual error message from the compiler?

That would help tell us what exactly the error you are getting is.

There is nothing wrong with the call to ShellExecute(). The error, as I've already pointed out, is in the call to GetChar(). Correct that and you'll be on your way.

Yes, but what over way can I get a char* from an ini file as that was the only function that I thought would work seen as I am storing characters in my ini file.
|
|

|

OK, then try GetPrivateProfileString
This returns a string from the ini file. I hope this will solve ur problem.

Unless you have a compelling reason to use the CIni class, why not simplify things and use GetPrivateProfileString() instead? Something like:
char szBuffer[128];
GetPrivateProfileString("History", "Input", "", szBuffer, sizeof(szBuffer),
"D:\\Programs\\Microsoft Visual Studio\\MyProjects\\Prog12\\Debug\\IniDemo.ini");
...
ShellExecute(...);

Thanks for the code David. In my ShellExecute where I want the value to go to I put szBuffer or what do I put please?

I do not know enough about the problem to answer this. For example, what does the .ini file look like?

My ini is like this but I have changed it from History and Input to the correct settings when getting the information.
[Settings]
Path=notepad.exe
Paramaters=
WorkingDirectory=
So in the ShellExecute I would want to get all 3 values and put them into the ShellExecute so it can run it.

|
|
|

char szPath[_MAX_PATH],
szParameters[_MAX_PATH],
szWorkingDir[_MAX_PATH];
GetPrivateProfileString("Settings", "Path", "", szPath, sizeof(szPath),
"D:\\Programs\\Microsoft Visual Studio\\MyProjects\\Prog12\\Debug\\IniDemo.ini");
GetPrivateProfileString("Settings", "Parameters", "", szParameters, sizeof(szParameters),
"D:\\Programs\\Microsoft Visual Studio\\MyProjects\\Prog12\\Debug\\IniDemo.ini");
GetPrivateProfileString("Settings", "WorkingDirectory", "", szWorkingDir, sizeof(szWorkingDir),
"D:\\Programs\\Microsoft Visual Studio\\MyProjects\\Prog12\\Debug\\IniDemo.ini");
ShellExecute(NULL, "open", szPath, szParameters, szWorkingDir, SW_SHOW);

Thanks for the help I really appreciate it and it works great.

One last thing actually. Is there a way that instead of having the ini path hard coded I can just make it look where the project exe is being run from and then just //IniDemo.ini?

Assuming that GetChar() returns a character and takes 3 char* as arguments, then the third argument is wrong. Of course the third argument would be wrong any way.
TCHAR('C') is equivalent to char('C') or (UNICODE) wchar_t('C')
_T('C') is equivalent to 'C' or (UNICODE) L'C'
_T("String") is equivalent to "String" or (UNICODE) L"String"
TCHAR("String") is invalid; because you are trying to convert a char* into a char.
Of course if your intention is to take the low-byte of the address of the string "NoneSet", then my assumptions are all wrong and there is nothing wrong with that line of code.
I am a day late, but I hope that helps.
